chrome freeze on console with novnc after restarting console

[Seyeong Kim]

[Impact]

after deploying openstack.

On, horizon, chrome freezes when restarting vm via console.

I analyzed something for this.

ubuntu's novnc version is 0.4.0 which is very old version.

test pkg 0.6.1 [1] is working fine ( need to remove cached data on chrome )

and 0.5.1 + commit[2] is working fine.

I tried backport this commit[2] to 0.4.0.

but it's too far from 0.4.0 and quite many different commits between them.

novnc may need to be upgraded to 0.6.1

Thanks.
